Awesome work!

I made it as a single patch for 2.x-cvs which also includes configure.in
modifications.

After applying the patch, be sure to run "autoconf" then you can
configure Nagios with JSON routines with:

./configure --enable-xsdjson

Configure will print the following near the end:
We'll use JSON routines (in xdata/xsdjson.*) for status data I/O...

Then usual make and make install to get everything installed.

I haven't tested it yet (lack of time) but it does build successfully
with JSON routines.

Enjoy

Thomas
